Adds context.withFreshWatchState/readFreshWatchState and sweeps the
remaining session-critical readers: context menu actions, folder tree
rows, discover hero, and TV spotlight minutes-left.
Delete the per-event list patching, parent-count adjustment, and the
screen-local progress overlay; rows and the hero resolve against
WatchStateStore at build. Also backfill parentId on playable-descendant
pages so hierarchy resolution covers season detail pages.
Cards consult the hierarchy-aware store so container marks flip episode
rows instantly and a stale per-episode patch can no longer shadow a newer
show/season mark; playback opens with the session-fresh resume offset.
Resolution now considers parentChain ancestors (newest event wins) and
watched patches set container leaf counts, so container marks reach
descendant cards and vice versa.
The side-nav host's onSystemBack called _handleMainBack on the system
route-pop path, jumping straight to the home tab and skipping the dpad
back chain (content -> top tabs -> sidebar). Restore the original inert
behavior: canPop:false blocks the route-pop and the key path owns the
chain; the host still closes an open sheet on back. Bottom-nav unchanged.
Both main_screen hosts (side-nav + bottom-nav) drop their PopScopes and
pass canPop:false + onSystemBack to OverlaySheetHost, so a system back
with a sheet open closes the sheet instead of running tab-nav/exit. Key
(dpad) back path unchanged; onSystemBack mirrors it for a pure popRoute.
hub_detail and media_detail (TV + non-TV) drop their hand-rolled PopScopes
and pass canPop/onSystemBack to OverlaySheetHost. Keeps appbar-focus-first
and Android-keyboard block behavior; fixes system-back-with-sheet-open
leaking to a screen pop. iOS swipe-back preserved.
watch_together, video_player, mobile_remote and live_tv_show_schedule now
pass canPop/onSystemBack to OverlaySheetHost instead of hand-rolling a
PopScope. Restores the iOS swipe-back on watch_together and centralizes
the sheet-close-on-back logic.
Adds nullable canPop + onSystemBack to OverlaySheetHost. When canPop is
set, the host installs its own PopScope that closes an open sheet on a
system/route back instead of popping the screen; null keeps today's
behavior. Lets screens drop their hand-rolled sheet-back PopScopes.
